摘要： A seal and seal assembly for use with well tools, such particularly as well packers, for sealing the annulus between the well packer mandrel and the wall of a well tubing such as casing. The seal is fabricated of an elastomeric-like material comprising fluorocarbon resins, poly arylene ketone, and carbon fibers mounted between end retainer assemblies each comprising a mesh anti-extrusion ring, a tapered mesh backup ring, and a metal backup shoe. The seal has internal longitudinally spaced V-shaped recesses to cause the seal to buckle radially outwardly as it is compressed longitudinally to increase the stress along the middle portion of the seal where the seal meets the well casing inner wall. The seal is useful at high temperatures and pressures such as 550 degrees F. and greater than 15,000 psi.
摘要翻译：一种密封和密封组件，用于井封装置，特别是封隔器，用于密封井封隔器心轴与诸如外壳的井管的壁之间的环形空间。密封件由包含氟碳树脂，聚亚芳基酮和碳纤维的弹性体材料制成，所述碳纤维安装在端部保持器组件之间，每个端部保持器组件包括网状抗挤压环，锥形网格支撑环和金属支撑鞋。密封件具有内部纵向隔开的V形凹槽，以使得密封件沿纵向压缩时径向向外弯曲，以增加沿着密封件的中间部分处的应力，其中密封件与井套管内壁相遇。密封件在高温和高压如550华氏度和大于15,000磅/平方英寸的压力下是有用的。

摘要： A hydraulically set well packer. The setting sleeve is releasably locked to the packer mandrel to prevent premature setting while the packer is being lowered to its desired downhole location. The setting sleeve is unlocked by increasing fluid pressure within the packer mandrel above a preselected value. The length of the setting sleeve can be easily adjusted to accommodate additional piston units, changes in mandrel length, and various packing elements.

摘要： A cementing tool for cementing a casing in a well has an inner mandrel that defines a central flow passage and has at least one fluid port defined through a wall thereof. An outer mandrel is disposed about the inner mandrel and the inner and outer mandrels define an annular space therebetween. The outer mandrel has at least one sealing element affixed thereto. An opening sleeve is positioned in the inner mandrel and is movable from a closed position to an open position in which the fluid port is uncovered. An expansion cone is positioned in the annular space. Fluid pressure applied through the central flow passage, and the fluid port will pass into the annular space and will urge the expansion cone through the annular space which will plastically deform the outer mandrel so that sealing elements affixed to the outer mandrel engage a previously installed casing in the well to seal thereagainst.

摘要： In a subterranean well a one-trip production zone perforation and proppant fracturing operation is carried out using a workstring-supported perforation gun lowered into a casing nipple located in the production zone. Firing of the gun creates spaced apart aligned sets of perforations extending outwardly through a side wall portion of the workstring, the nipple, the surrounding cement, and into the production zone, after which the gun falls into and is retained in an underlying gun catcher portion of the workstring. While an overpull force is maintained on the workstring above the perforations, a proppant slurry is pumped down the workstring, out its sidewall perforations, and outwardly through the aligned perforation sets formed in the nipple, cement and production zone. After stimulation of the production zone, the workstring and the spent perforation gun that it retains are pulled up, with the upwardly moving workstring positioning a sliding closure device inwardly over the perforations to isolate the stimulated production zone until the well is readied for production. Illustrated alternate embodiments include the use of a low debris casing gun in place of the drop-off type perforating gun, the use of pre-formed wide wall perforations in the workstring side wall, and a one-trip perforation and production flow creating method in which the production zone stimulating step is eliminated.
摘要翻译：在地下井中，使用下降到位于生产区域中的套管接头的工作支撑穿孔枪进行一次性生产区穿孔和支撑剂压裂操作。枪的射击产生间隔开的对齐的穿孔组，其穿过工作绳，乳头，周围水泥的侧壁部分向外延伸，并进入生产区域，在此之后，枪落入并保留在下面的枪夹部分的工作字符串。虽然在穿孔上方的工作绳上保持过大的力，支撑剂浆料沿着工作绳排出其侧壁穿孔，并向外通过形成在乳头，水泥和生产区域中的对齐的穿孔组。在刺激生产区之后，将其保持的工作绳和用过的穿孔枪拉起，向上移动的工作系统将滑动闭合装置向内定位在穿孔上方，以隔离受刺激的生产区，直至井准备生产。示例性的替代实施例包括使用低碎屑套管枪代替脱落式射孔枪，在工作侧壁中使用预先形成的宽壁穿孔，以及一次穿孔和生产流程创建方法生产区刺激步骤被消除。

摘要： A packer slip has multiple anchor studs which are press fit in an interference union onto a slip plate constructed of a corrosion resistant alloy material. The anchor studs are located on the slip plate in such a manner as to distribute applied load forces evenly onto the well casing. The anchor studs have ribs formed by longitudinal serrations, with the stud body and ribs being truncated along a planar face, thereby producing a cutting edge for penetrating and gripping a well casing, which is also constructed of corrosion resistant alloy material. The ribs are separated circumferentially by longitudinal grooves formed in the main body portion of each stud. According to this arrangement, the grooves provide flow space for rib material which flows in response to compression forces arising as a press-fit interference union is produced. Each stud is made of a material which has a hardness which is substantially greater than the hardness of CRA alloy casing material, such as carbide compounds including refractory carbides and cemented refractory carbides.
摘要翻译：封隔器滑动件具有多个锚固螺栓，它们与抗腐蚀合金材料制成的滑板压配合在干涉接头中。锚栓位于滑板上，以便将施加的载荷力均匀分布到井套上。锚钉具有由纵向锯齿形成的肋，其中螺柱主体和肋沿着平面被截顶，从而产生用于穿透和夹持井外壳的切割边缘，该外壳也由耐腐蚀合金材料构成。肋条由形成在每个螺栓的主体部分中的纵向槽周向地分开。根据这种布置，凹槽提供用于肋材料的流动空间，其响应于产生压配合干涉联合而产生的压缩力而流动。每个螺柱由具有基本上大于CRA合金外壳材料的硬度的硬度的材料制成，例如包括难熔碳化物和水泥耐火碳化物的碳化物化合物。
